1989 GTI Instrument Panel

On my '87 GTi, the trim piece that goes around the instrument cluster, heater controls, stereo etc. is held in with spring clips (unlike on the Jetta, where there are screws). Carefully pry it straight out. Then remove the switch for the headlights and the bracket that holds it (one or two screws, can't remember). Then you can tilt the instrument cluster out, top first. The speedometer cable needs to come off to get the cluster out far enough to change the bulbs. Some models also have a vacuum hose attached to the back of the instrument cluster. The bulbs are special bayonet mount mount bulbs that you can not get at regular parts stores. The dealer will have them as will parts stores specializing in VW. There are several bulbs along the top edge of the instrument cluster and another few at the back of the cluster.

When one of mine broke last year, I replaced all of them, the additional expense justified by not having to open it up for another 16 years (I wish, anyway).

You have to take the trim off, 2 screws on top, two on bottom...then you have to disconnect the speedo cable, then the wireing harnesses....then pull the cluster out. from their you should see either green or orange plastic thumb screws (those are the lights) just turn them and out they will come.....install same as reverese of process.....however the speedo cable can be pain to put back on.
